(liter/nu MATHEW mnoaiasjniaxm, or sroxliivn, wasmaeao g al Z whom itmay concern} Be. it known that I, MATHEW- LARKIN, a citizen of theUnited States, re-

sidingat Spokane, in the county of 'Spokane andState of Washington, haveinvented a; new and useful Rerailing-Frog Holder, of which the following"is, a specifi cation,

This invention relates to improvements in means forholdingjre-railingfrogs which are now usually anchored by spikes, to theties. r V

When alocomotiveorcar has beenejdef railed, great difficulty isexperienced inreirailing the locomotive oncar forthe prini cipal reasonthat it isdiflicult to properly o anchor the re-railing frogs. The.wheels of a-de-railedcar or locomotive may bespnk;

deeply. in the earth between the ties orthe latter maybe so rotted andoldas to afi'ord.

no means for holding spikes driven; there- 7 into. When the wheels ofade-railed car are is also necessary to hold the re-railingfrogs.against longitudinal movement resulting;

from ride-up thrust of the wheels imparted thereto.

Q spikeanchorage, but further, the de-railed Vehicleseldom stops in suchrelation to the ties as Q to permit the rep-railing frogsforratherrtheir spike openings, from-properly registering with the ties.

' Now the primary object of this invention;- broadly speaking, is toprovide. means for anchoring a re-ralling frog to a rail so that thelatter will provide a continuous and ever: present mounting irrespective.ofthe condi-E- tion of the ties toanchor; the; frog thereto either- 7inparallel or angular'relationto the rail, the said means not onlyserving-to retainthe ire-railing frog in such relation to the rail, butalso, to prevent longitudinal movement of the frog under wheel ride-upthrust H More specifically speaklng, my invention I has to do with meansengageable with the n It will now beclear that theties. not only failfrequently'to offer the requisite nnitArilrne-snoe HonnEn.

Like characters' ofreference designate similar parts throughoutthefdifl'erentj figures ofthe drawing. I

As illustrated, 1 the'lties designates the left-hand railwhich ismount-T ed on the ties and anchored theretoas usual,

by-spikes 3: A re-raiIing L-left-hand frog this shown disposed insubstantially parallel relation to, the rail with,, the fends' thereof Imounted upon adj acentties but not in any wayspiked or secured-thereto.It-will be seen that-in this position, the spike openings 5,-atoneendofthefrog, overhangthe tiesothatthey would be unavailable in anchorling, the frog, Thesefrogs, of the'most reg oentand universal type, aremade of pressed L steel-and they are in the form ofelongated hollowbodies, open atthe bottom, J Injorder" I to sustain the great, weight towhich -;they are usually; subjected, these frog bodies, are

universally stiffened by transverse ribs or,

, webs 6, 7, 8 and 9,'asillustrated forexample in the accompanyingdrawing. v The frog has an end-wall 10 and the top 7 portion is providedwith a re-railing guideway 11 which is diagonally arrangedlongitudinally along the top of the frog, said top sloping downwardly toan edge- 12 adapt. ed to receive the foremostwheel; Thesi'dewalls of thefrog are indicated at l3v-and lt and the bottom of the frog isprovidedwith studs 15, as shown] flVhile my invention does not reside in there-railingfrog, so

much of the same has been described to rel}..-

der the deviceof my invent n clear. inits application thereto.

As illustrated, he means for anchoring the frog to the rail comprisesone or more devices-which may comprise strips of heavy metal; asindicated at 16, one end thereof being shaped to embrace the head orball of the 'r2'til ,"lan'd the other end thereof being shaped to engagethe bottom and a sufficient extent of the interior of one side-wall ofthe frog so as; to 'extend upwardly between the sti fi'ening'webs, asindicated at 171 The] terminal end 1? is practically in the form of'ahook and the strip 16is desirably, 'although not necessarily-,"of' suchlength that the" bight 18-, of tl ie'hooln is slightly inclinedandpro'portionedto fit in super-posed supported'relation on the innerflange 19, of the rail 2i Thus the frog holding "device will no'tonly-be supported a't'its frog enga ging'end, but the'lfrog'itself,as-re'gards ments of any kind will be necessary. All'of .the' 'iail"holding devices are identical in formation'except'ing for the terminal17 of that device which is disposed nearest theendwall' 10, anddesignated at'23, this terminal being'longer than the terminal 17 of itscompanion device so that it will not release engagement when the frogendlO istilted upwardly as awhgeel begins to ride up onthe lower end 12.These holding devices preferably fit the ball of the rail'in such mannerthat they can be adjusted by slid- V 3 ing them along the rail forengagement interiorlyI of the frog at desired points with respect "tothe reinforcing Webs thereof; Thus intheillustration, one ofthe devicesis'enga-ged with the frog behind web 8, with.

' respect to the direction of Wheel thrust, and

the otherc'levice 'is engagedbehind web 6, with respect to the directionof said thrust.

I Will now describe one of the particularly advantageous and broadlynovel features whereby these normally loosely applied frog holdingdevices friction-ally wedge themselves ininunovable anchorage connectionwith the ball of the rail responsive to and as a result of. any wheelthrust imparted to -Such wheel thrust would invariably tend to. shiftthere-railing frog longitudinally .inthe direction of the arrow.

' shift the devices out of right angular relationto; the rail, andfin sodoing, the diagonally opposite margins would necessarily tend tobite'orwedge "against the-ball faces.

The very loose; connection hereinbefore referred to, facilitates thisgripping action to prevent shifting movement of the holding devices.Furthermore, in view of the fact that any shifting movement imparted tothese' devices weuldbeapp licd to the'lower end thereof, below-the ballof the rail, it is essentialtopreven aid fd'evices from tilting onthetop of the rarlwithportions28 as the fulcrums. Therefore-,to avoidsuch defective-action, I provide the retaining terminalsZQ, equal inwidthto the widths of the strip of'which-theholding device is made, thisretaining dev-ic'e engaging the rail ball at one of its undfer faces toprevent tilting movement of the holding devices. The greatest end thrusti s app'lied when the first wheeljbegins to ridefup on the frog, butthere will be a certain amount of end thrust as a result ofride-upengagement of the next following wheel. I However, with thetremendous weight of one wheel on the frog,

the following end thrust will not usually be as great asthe initialthrust.

' While? in l, I have shown the. re-railing frog'in parallel relationwith the rail, and being held by'twodevices, it will beHITClGIStO-Odthith -"Qnfifof said devices will be sufficient when it-isdesired to swing the lower. end lQaway from the rail to register with .a.de-railedtruck wheel located a considerable distance fronithe rail, asshown in dotted linev in Fig. Thus; I do not wish to; be confined to theuse of two holding devices. fereach frog. It will also be understoodthat while I have only shownmy invention applied to a left-hand frog,its application'toa right-hand frog will be identical and thereforeneednotibfe illustrated.

I also assert that my invention is novel as an article of manufacture,one phase of novelty being a single device having porlimited theretoexcept for such limitations as the claims may import.
